(Yes, I am encouraging her to join APUG and ask her own questions)
It's been my experience working with several different enlargers with different dichro heads that grade 5 contrast can't be matched by setting maximum magenta filtration that one can get by using grade 5 VC filters.

One can still do split filtered printing with dichro heads but without the range of contrast expected with VC filtration.

But I have to say that split filtered printing really isn't necessary.
